~x-ai/grok-latest → A (5:1)

Commit A redesigns the CLI surface (forum list/show/post subcommands, required tag/--delegate on post, dropped freestanding ingest) and keeps docs, server next-move strings, and integration tests aligned—lasting product/API structure. Commit B only collapses hand-enumerated Kaocha suites into one `^test\..+` pattern in tests.edn, a useful but small test-harness maintenance fix.
